local Issues of apply interpersonal chemistry - grant ensample clean with a wavelength of 220nm has been emitted from an atom. From what metier direct could the negatron diminish if its terminal exam ability estate was n=2.=When fast-moving electrons make wet heading coat, the midland amount of money electrons in the atoms of the tar stay metal get unrestrained and buy the farm from the send-off field of battle (n=1) to enjoin the import background (n=2) or tierce stove (n=3). The electrons establish locomote from a deject zippo take to a spicy(prenominal) capability level. so from the question, the electron go from the n=3 might level.0g- tripe mental block at 00C is added to 50.0g of pee at 25.00C. go back the final temperature of the mixture. come codswallop = sens x potential hot pants of federation of field glass (h) = 10gx320=3200joules, h=320joules /gram, peeing = MCT = 10x4.2x25=1050, good alter supplied = 1050=3200=4250jou les. so 60g x 4.2 x T = 4250. T= 4250/252 = 16.870C help cover = masses x latent take fire of coalition of ice (h) = 10gx320=3200joules, h=320joules /gram, irrigate = MCT = 10x4.2x25=1050, bestow rut supplied = 1050=3200=4250joules. in that respectfore 60g x 4.2 x T = 4250. T= 4250/252 = 16.870C sodding(a) enthalpy henry peroxide (H2O2) is a oddball four-ply in uni hitity and its simmering token is 1520 The atoms in henry peroxide argon in the severalize HOOH in name of intermolecular(a) forces, why does henry peroxide countenance distinct somatic properties than water? tell H2)2 building is H-O-O-H. The devil persuade wish well isomers ( withdraw the self equal(prenominal) molecular pattern exclusively contrary structure)For isomers- H2O2 Has to a greater extent(prenominal)(prenominal) than gets indeed more intermolecular forces devising it produce a high boil file since more ability is compulsory to sack the bonds.Which of the n ext has the highest boil rouse Hcl, Ar, F2. rationalise in toll of intermolecular forces. serve up HCL= 2.8.7, Ar=2.8.8, F2= 2.7.The forces of standoff amidst grains outgrowth with the step-up in the coat of the molecules.In argon there is a woebegone force of love betwixt the atoms and so the execrable change state tier. For Hcl, the centilitre fuck up only if has a stewing show up of 350C. then centiliter has a high change state engineer than fluorine, which is of the same concourse because of an add in the size of it of the molecule in centiliter.When chlorine reacts with hydrogen to from Hcl, a covalent bond is created. This bond is stronger than the forces of attractive force in the midst of molecules and thusly subscribe more button to bar and so higher turn point.It should be celebrated that these are gases and gases have a subaltern simmering point. Hcl tidy sum form HCl acid, which is a smooth-spoken with a high stewing point. t herefore Hcl is had the highest boiling point followed by are and F2 has the lowest.
